The transient response is decent on all rails except 3.3V, where the deviation in percentage may not be among the highest, but the voltage still drops below 3.2V in both tests. A higher nominal voltage of 3.3V would help maintain regulation control.
Transient Response ATX v3.1 Tests
The PSU passes all ATX v3.1 transient response tests. Here, this Gamer Storm unit performs much better than the Focus GX-1000 that I tested several months ago. The changes in parts and/or the setting of the resonant controller can be the cause. In any case, the increase in performance is highly welcome.
The 12V rail’s performance is high on all load ranges.
